✦ Synopsis
The kinetics of the copolymerization of styrene with pure p-and m-divinylbenzene accompanied by phase separation and gelation were studied. The concentration of monomers was determined at intervals by gas chromatography, and the content of pendant double bonds was characterized by Raman spectroscopy of the copolymers. Further investigations on the mechanism of network formation were carried out. The reactivities and crosslinking efficiencies of p-or m-pendant double bonds were compared, and an explanation for the relationship between structure and function is proposed.
